NOTES ON THE BIRDS OF THE STATES OF PERNAMBUCO AND PARAIBA, BRAZIL

BY DONALD W. LAM•I Is their 'Birds of Lower Amazonia,' Griscomand Greenway (Bull. Mus. Comp. Zo61.,88, 1941) refer to this regionas a "neglectedcorner of Brazil," a statement borne out by the number of new forms and ex- tensionsof range in the small collectionmade by the author.z It is for this reasonthat the writer ventures to submit the following field notes and observations on birds encountered in the . The of ,where the writer was located,is in the state of Pernambuco,on the coast,about eight degreesbelow the , and almost at the apex of the 'bulge' of northeasternBrazil. The rainy seasonin this commencesabout March and lasts until the end of . The climate is moderatethroughout the year, but some- what coolerduring the rainy season. Mean temperature is 82 de- greesFahrenheit. The lowestrecorded temperature is 52 degreesand the highest 103 degrees,but the normal variation is between 70 and 95 degrees. This region offers a number of varied habitats within closeprox- imity to one another. Of these, the ocean and beach are the least profitable for the bird observer. Pelagic speciesare rarely seen,and their appearancesare almost exclusivelyconfined to the months of April and May whenoccasional birds are blownin by storms. Frigate Birds, Boobies and Brazilian Cormorants have been noted, as well as a petrel tentatively identifiedas the Trinidad Petrel (not in- cluded in the following list). Shore birds are fairly commonon the beach in season. Immediatelybehind the beachis a fringe of coconutpalms, stretch- ing inland for about half a mile. Most of this regionis inhabited, and there is somecultivation, principally of mandioca. Certain tanagers, flycatchers,the , ,parrakeets and the house wren are most common in this section. Severalsmall rivers empty into the oceanin the vicinity of Recife, usually borderedby fairly extensivemangrove . There are also a number of small fresh-water marshes. The latter particularly supportan abundanceof aquaticspecies, including rails, herons,king- fishers,ducks, gallinules, a grebeand numerousmigrant shorebirds. Further inland there is a large area of semi-opencountry, someof which is planted with mandioca and other crops. Seedeaters,fly-

Zimmer in the Proceedings of the Biological SOciety of Washington, 60: 99-10•. 1947. 262 L•, Birdsof Pernambuco andParaiba, Brazil tApril[Auk catchers,anis, guiras, tanagers and doves are the most conspicuous birds of this section. Isolated wooded patches are scattered about this semi-opencountry, usually on the tops of small hills. They sup- port an entirely different type of bird life, includingnumerous small jungle flycatchers, -creepers,, , and woodhewers. A number of trips have been made to a jungle area near the town of , about forty miles north of Recife. Such species as cotingasand •aris were found primarily in this area. The interior of the statesof Pernambucoand Paraiba is usually arid, and is known as the Sert5o. The terrain is frequently rocky and the consistslargely of and low brush with some densehigh thickets and occasionallight woods. This regionsupports a number of speciesnot found on the coast, such as the rico-ricoand the . The most prevalent Sert5o birds include Brazilian Cardinals, several speciesof doves, mockingbirds,orioles and the omnipresentvultures and caracaras. Over a period of more than four years, the writer has spent approxi- mately 450 hours in the field. At various times he has been accom- paniedby LieutenantE. Pfeiffer(U.S. Marine Corps),Lieutena•t DonaldAlexander (U.S. Army), CaptainFrank Connor(U.S. Army), LieutenantGeorge Cummings () and Mark Taylor (Rubber DevelopmentCorporation), whose able assistancehas made this paper possible. Much welcomeaid and encouragementhas also been supplied by Dr. Herbert Friedmann, Curator of Birds at the U.S. National , who has struggled with poorly worded de- scriptionsand badly damagedspecimens. The followinglist is by no meanscomplete for the region, as only those speciesobserved and definitely identified by the writer are in- cluded. Data for the coastalregion are fairly representative,although somespecies, such as Trogonvariegatus, which are known to occur in this part of Brazil, have not been seen. Material on the interior is necessarilyvery incomplete,since it is basedprincipally on occasional trips. The rltea,for example,is not uncommonin centralPernambuco, but I have never encountered it. Certain material has also been de- leted from the paper becauseof lack of corroborative specimens.

TINAMIDAE. Tinamous. Crypturellussoul albigularis(Brabourne and Chubb).--Fairly com- mon in heavy jungle at Goiana. Also at S5o Caetano in high brush about 100 miles inland.

Botauruspinnatus (Wagler).--Fairly common,and noted regularly in one large brackish swamp. Some of these occurrences,however, doubtlessrepresent repeats.

ANATIDAE. Ducks Dendrocygnaviduata (Linnaeus).--Large flocksare to be seenin the brackish marshes from the middle of September to April. These flocksbreak up and the birdsbecome more widespread during the rainy season. A nest containingeleven eggsin a fairly advancedstage of incubationwas found at the edgeof the swampon September17, 1944. These duckswere fairly commonat Paros, Paraiba, on August 13, 1944. Dendrocygnaautumnalis discolorSclater and Salvin.--Uncommon near the coast, but about 4,000 were seen at the lake at Candado in western Paraiba, October, 1945.

ACCIPITRIDAE. Hawks, , etc. Elanus leucurusleucurus (Vieillot).--Seen on four or five occasions, usually over semi-opencountry. Harpagus bidentatusbidentatus (Latham).--One was shot in dense jungle at Goiana in October, 1945. Apparently not common.

Falco sparveriuseidos Peters.--Fairly common throughout the in- terior and noted in the most arid sections. Also occasional in grasslandsnear the coast.

RALLIDAt•. Rails Rallus longirostriscrassirostris Lawrence.--Five of these large rails were found in a small sectionof grassymarsh on January 16, 1944. In view of their readinessto take wing instead of skulking when ap- proached, it is consideredpossible that the birds might be migrants. They were noted again in the same marsh on January 21, 1945. Porzanaalbicollis albicollis (Vieillot).--Easily the commonestspecies of rail in the region. A femaletaken in August, 1943,had in the ovary two eggs complete except for shells.

Also common in the Sert•o, where every pond, however small, seemsto have at least one pair. Squatarolasquatarola (Linnaeus).--Two birds in plumage were found on a sand spit on May'21, 1944. These birds are fairly common winter residents. The earliest fall record is September 9, 1945. Charadriushiaticula semipalmatusBonaparte.--Flocks of 50 to 100 migrant shorebirds,including this and the preceding species,as well as Sanderlings,are often to be seenon the beachesin March and April. Exact fall dates are not available for this species,which appearsto be somewhat less common than C. wilsonia. Charadriuscollaris Vieillot.--This residentspecies is fairly common throughout the year, being found in the same areasas thosefrequented by the migrants and also further inland. A specimentaken on June 29, 1945, was approaching breeding condition. One was taken in August, 1944, at Paros, Paraiba, about 160 miles inland. Charadrius wilsonia wilsonia Ord.--Noted in mixed flocks from September23, 1945, throughout the winter. The latest date was supplied by a specimencollected on May 21, 1944. Compared Birdsof Pernambuco andParaiba, Brazil 267 with North Americanspecimens this bird is nearestto typical wilsonia, but has the white frontal band narrower but not so narrow as in beldingi. Further material should be of interest.

Sco•o•,AcmA•. Sandpipers Numenius plmeopushudsonicus Latham.--A fairly common species in the tide-water mangrove swamps throughout the winter, but it is very shy. The earliestfall date is September23, 1945. Tringafiavipes(Gmelin).--Fairly common. Noted from 14 through April 15 in brackish and fresh-water marshes.

Tringa solitaria cinnamomea (Brewster).--Common from early November to the middle of April, principally in fresh-water marshes. One collectedApril 16, 1944, was in breedingplumage. This species was very common along a small stream in the arid interior near S•o Caetano on February 26, 1946. Actitis macularia (Linnaeus).--One was shot along the bank of the Paraiba River near Jo•o Pessoa on October 11, 1943. Others were notedin January and February. Arenaria interpresmorindla (Linnaeus).--Two small groupsof three and four birds, respectively, were noted in a tide-water mangrove swamp on September 23, 1945.

A female in breedingcon- dition was shot June 4, 1945. , Capella undulata gigantea (Temminek).--Uncommon. Only two birds were seen---onecollected July 16, 1943, and the other September 15, 1943, both in a small fresh-water marsh close to the Recife airfield.

COLUMBIDAE. Pigeons Zetaida auriculata noronha(Chubb).--Several small flockswere ob- servedat Patos,Paraiba, in the high Sert•o on August13, 1944. Very common on the Pernambuco-Paraiba border about 150 miles inland in October, 1945. Local sources state that enormous flocks of this are present in the Sert•o during August and September. Scardafellasquammata squammata (Lesson).--Common in the palm fringe, although less so than passerina. A nest with two young was found in a palm tree on May 21, 1944. This speciesis abundant throughout the dry interior. Columbigallinapasserina griseola Spix.--Very commonin the palm fringe and abundant in open fields. Also commonin parts of the interior. Nests were found, usually on the ground, throughout the dry season,from the middleof Septemberuntil the end of April. One was discoveredon August 4, 1945, during the rainy season,containing two eggs. The nests were constructedof dried grass, and, though rather untidy, were better made than is usualin this genus. All but one were found on the ground. The exceptionwas rather crudely built with dried reeds, and was in a crotch of a fallen branch about a foot above the water in a marsh. In no instance did the number of eggsexceed two. A nest locatedon November 2, 1943, containedone eggand oneyoung bird, evidentlyvery recentlyhatched. It was 11• incheslong and sparselycovered with buff-coloreddown.

Myromotherulaaxillaris luctuosaPelzeln.--A commonspecies in the jungle whereit is normallyfound in lower growth. Sometimespresent in mixed feeding flockswith Xenops and other insectivorusbirds. Myrmorchilusstrigilatus strigilatus (Wied).--A ground-hauntingant- bird which was almost certainly of this specieswas fairly commonin the densebrush at SiIo Caetano. Several specimenswere examined. It was not found along the coast. Formicivoragrisea grisea (Boddaert).--Rather common. Usually encounteredin the jungle, but occasionalalong the coast in thick ß brush. It was taken also at S5o Caetano. Pyriglenaleucono• pernambucensisZimmer.--Common in the thick jungle at Goiana, but only taken once in jungle sectionssouth of Recife. A ground species.

CONOPOPHAGIDAE. Gnat-eaters Conopophagalineaa (Wied).--Four fully-grown immature birds werefound in the jungle near Recifeon Apr/130, 1944. Severalothers were taken later in densejungle, but this gnat-eater is not common.

COTINOIDA•. Chatterers Xipholena atro-purpurea(Wied).--Several specimenswere collected in thick jungle at Goiana. This speciesis confinedto large jungle areas. Pinto (Caalogodas Aves do Brasil) wasof the opinionthat this cotinga was extinct in the northeast.

PIPRIDAE. Manakins PiPra erythrocephalarubrocapilla Temminck.--Fairly common in low densejungle. Chiroxiphiaparcola parcola (Linnaeus).--Common in low jungleat Goianaand fairly commonin similarareas south of Recife. Courtship dancingby this specieswas observed for abouthalf an houron January 22, 1945. Four males and one female were present, but two of the males were merely onlookers. The other two used a small horizontal branch about two feet above the ground. They perchedparallel to one another, and first one and then the other would jump about a foot in the air, beating his wings violently and uttering a purring note. Frequently they would jump over one another. When the female, which was silent throughout,alighted on a branch dose by, they usually deserted their perch and demonstrated on each side of her. When sheretreated they returned to the original branch. Finally she alighted on the perch and both faced her and danced violently. This occurredseveral times until onemale finally left (not visibly driven off) •74 LAMM,Birds of Pernambuco andParaiba, Bragil [April[Auk andthe f•male remained on the branch, posturing and hopping a little, while the male danced excitedly about her. Three or four times he darted to a twig about six feet away but returned immediately. They finally copulated twice in closesuccession, after which he flew off, but she remained for about a minute longer. All birds then desertedthe area, but a male returned shortly thereafter and began calling. Manacus manacusgutturosus (Desmarest).--Common in all jungle sections. Mating display was observedin early October. TYRAI•N•DAI•. Tyrant Flycatchers Fluvicolapica albiventer(Spix).--This flycatcheris unknown on the coast but is common in the interior, where it is found side by side with climazuraand apparently replacesleucocephala. Noted at S•o Caetano but no nearer to the littoral. At S•o Caetano it was outnumbered about five to one by dimazura. Whereas dimazura runs along the ground seekingits food, albiventeris inclined to perch on a twig close to the water and catch flies in the air. Fluvicolaclimazura climazura (Vieillot).--This ground flycatcher is the commonestbird about the streets and of Recife. It is also very common throughout the coastal zone, and moderately so in the interior. It is particularly partial to localities where there is water, and is confinedto suchsections in the Sert•o. A nest containing almost grown young was found on October 24, 1943. Another nest in process of was found in a swamp on April 23, 1944, and a nest with one egg on January 20, 1946. Nests were noted at heights vary- ing from twelve to three and one-half feet above the ground, and were always in the vicinity of water, usually at the end of a limb with the entrancefacing outward. They are coveredat the top, and are nor~ mally constructedof dried grasswith some near the entrance, and are lined with feathers. A rundinicola leucocephala(Linnaeus).--Very common in marshy sectionsbut apparently confinedto the coast. A nest containing two eggswas found on November 14, 1943. Numerous nests were under constructionduring the latter part of April, 1944, and a nest visited May 28, 1944, contained three eggs. The nests are to be found in bushesin the swamps,usually not over four feet above the ground. No attempt is made to concealthem, and they are invariably very conspicuous. The nestsare very well made, and are roofed, with the entrance at the side. They measureabout four incheshigh, and about three wide, and are constructed principally of dried grass. The chamber is thickly lined with soft substances,usually some type of down. Vol,1948 65'[/ LAi•i•,Birds of Pernambuco andParaiba, Brazil 9.75

Pitangussulphuratus maximiliani (Cabanisand Heine).--This large, noisy flycatcher is found most commonly in the palm fringe and somewhatless frequently in semi-openareas, and was observedat Paros, Paraiba, and in other parts of the interior. It was also noted on the reef about 100 yards offshore,feeding on marine life. Nests containingeggs have been found during March and April. Four eggs appear to comprisea normal clutch. A typical nest, found March 7 in a caju tree was close to the end of a limb, about fifteen feet above the ground. The entrancewas on the side away from the trunk. It was ten inches in diameter, and was composedof twigs, dead vines, and a few pieces of paper. It contained two eggs and two freshly hatched young. Cnemotriccusfuscatus bimaculatus (Lafresnaye and d'Orbigny).-- Uncommon. My only record is of a female with ovaries slightly en- largedwhich was shot in densejungle just southof Recife on , 1945.

They were usuallyfound in small groups and frequented low bushes.

Co•R•mI)X•. Honey-creepers Coerebaluteola chloropyga (Cabanis).--Abundant, particularly in the palm fringe, but also found in jungle. Common in the city parks. Apparently rather rare at S•o Caetano. Nesting takes place through- out the dry seasonin the coastal zone, but is particularly noticeable in March and April. However, one nest with three young was noted on November 2, 1946. It has been observedthat this speciesfrequently builds in closeproximity to hornets' nests. The nestsare usually not more than ten feet above the ground, and are often in caju trees, but are sometimesin the cavesof houses. They are constructedof twigs, and usually lined with palm fiber. On April 7, 1944, nest building operationswere observedfor several hours.

Dr. Friedmann, in a letter to the writer regarding this bird, stated that "this constitutesa very remarkable extensionof range. This species was not known previouslynorth of extreme southeasternBrazil. In 280 •.•,,•, Birdsof Pernambuco andParaiba, Brazil tAoril['Auk view of the fact that farther south this speciesis parasitic almost ex- clusively on Molothrus badius, it is of interest to find that its range extends northward to include that of M. b. fringillarius." It is not yet known, however, whether it parasitizesthe latter form in eastern Brazil. Molothrus badiusfringillarius (Spix).--A specimenwas obtained from a flock of about 20 birds in brush country 40 miles southwestof Recife on June 18, 1944.

Dr. John T. Zimmer, in a letter to Dr. Herbert Friedmann, dated April 17, 1947, made the fol- lowing commentsregarding this spedmen. "I cannot match it exactly in our series. It is a young male and from its black bill and large size must be referred to ½unless it belongsto an unknown new form. It hasnever been recorded from the neighborhoodof Reeifeor any- Wherenorth of Bahia so there is nothing on record to give a clue. I should not be surprisedif it were simply the Bahian subspeciesfrom a new northern locality."
